Tsurumi 80PUW22.2 Stainless Steel Auto-Alternation Submersible Pump for Wastewater Handling with Vortex Impeller

Automating stormwater drainage and high-volume wastewater transfer with dual-pump redundancy requires a high-capacity solution with integrated auto-alternation control. This auto-alternation submersible vortex pump is configured for duty-sharing operation, making it ideal for managing aggressive liquids in large-scale commercial sumps. Its robust construction and vortex hydraulics ensure consistent performance in coordinated systems where manual oversight is not feasible.

Driven by a 2.2 kW / 415v three-phase motor, the system delivers a maximum flow capacity of approximately 800 L/Min and achieves a peak head of approximately 18.5 m. The auto-alternation control circuitry allows for dual-pump coordination, providing start and stop based on liquid level. This power rating facilitates high-pressure discharge through an 80 mm bore for effective coordinated vertical transfer.

The hydraulic configuration utilizes a vortex impeller manufactured from glass-fiber reinforced PA+ABS, enabling the passage of large solids up to 46 mm. This recessed design minimizes mechanical contact between debris and the impeller, significantly reducing erosive wear during continuous operation. The vortex behavior ensures stable hydraulic efficiency and prevents obstruction when managing high concentrations of stormwater in automated redundant cycles.

Mechanical integrity is supported by a 304 stainless steel and resin frame, with a double-face mechanical seal located in an oil chamber featuring an Oil Lifter. Protection is enhanced by a circle thermal protector built into the motor housing and an anti-wicking cable entry block. The unit utilizes non-toxic liquid paraffin as a lubricant, ensuring the pump is suitable for applications where liquid contamination must be avoided.

FEATURES

• Auto-alternation control facilitates duty-sharing dual-pump operation for redundant stormwater drainage.
• High-grade 304 stainless steel and resin construction offer exceptional corrosion resistance for wastewater applications.
• Vortex impeller made of glass-fiber reinforced PA+ABS enables a 46 mm solids passage without internal clogging.
